The present invention relates to ,a ceiling apparatus designed broadly for forming flat coils ofaflexible material as the same, isfed or delivered thereto. It. relates more particularly to an apparatus'for coiling flexible tubular bodies such as hose as the same is manufactured, treated or finished. I

7' Thelprincipal obj ect of the invention 'to provide an apparatus autolnatidin its operation for coiling the flexible body, and

Anotherjobj ectof the invention is to provide anautomati'c apparatus for theipur'pose described, and wherein the speed ofjtravel of the feedingappara tus or 'conveye1"- fra'me, radially of the coil 7 ing table is controlled by the speed or rota! 'tion of theeoiling table.

point of delivery on to the table gradually moves from the center outwardly to the periphery of the table forming one flat coil, and then reverses and travels inwardly forniing another fiat coil superimposed on the coil below. This operation continues automatically until the desired number" of" coil layers are provided. With thewfeeding or the delivery of the material on to the table being constant, it will be apparent that the coils will be more rapidly formed nearthe center of the table than adjacent its'per-iphery, and to compensate for thisiicondition it will be observed that by drivingthe shaft 18 through gears receiving their power from the opera-i tionof the table, the sleeve 19 travels at a V greater speedlongitudinally of its shaft when near the shafts innerend than; when adjacentitsoutere'nd. 1
